and articles formed with my artificial fiber wood.

Figure 1 is a front perspective view of my novel structure as 4appliedin an ornamental drawing room desk, a major part of which is formed withmy fiber wood.

Fig. 2 is a section on line m2, Fig. 1.

Fig. 3 is a perspective View of the skeleton frame employed inconstruction of desk shown in Fig. 1.

Fig. 4 is an elevation of an artificial arm formed of my fiber woodstructure, parts being in section to show the arm socket at theshoulder, and-the joint connection at wrist and elbow. Pulps asheretofore employed, have been compounded usually for a specific purposeFig. 5 is an v,enlargement of the hand shown in Fig. 41' with wrist andlower forearm in section to show detailed construction and joining ofparte.

Fig. 6 is a slde'elevation of an artificial foot and lower limb, formedwith my fiber wood construction, partly in section; different positionsof foot being shown by dotted lines.

Fig. 7 is a section on line m7, Fig. 6.

Fig. 8 is a front elevation of an artistic mirror frame formed of myartificial fiber Fig. 9 is a section on line ai", Fig. 8.

Fig. 10 is a front View of a tile or decorating plate formed of myartificial fiber wood structure.

Fig. 11 is a section on line Fig. 10.

Fig. 12 is an axial section through a bath tub formed of my artificial'fiber wood structure.

Fig. 13 is an axial section through a leg for furniturev constructioncomposed principally of'my artificial wood and showing a reinforcedcenter staff therein and a caster attached to the staff.

In preparing the composition I prefer to use the ingredients in aboutthe following proportions, the parts being given by weight as follows:viz: fifty-six pounds of fiber pulp, thirty-four 'pounds of magnesiteand ten pounds of asbestos mixed with liquid magnesia chloride 22o Baumeto a consistency adapted to fulfill requirement-t to pour or to make apaste or dough to be molded.

Good results may be obtained, however, when the ingredients are variedwithin' the following limits: fifty to sixty pounds of fiber pulp,thirty to forty pounds of magnesite and five to fifteen pounds' ofasbestos l Baume to requirement to pour, or to form a paste ordough tobe molded.

I obtain my ber pulp from any fibrous material, such as waste wood orlumber, saw dust, paper, straw, leaves, cane or corn stalks, properlydisintegrated. This ber I combine with t-he other ingredients as beforestated and mix to requirements.

When my articial ber wood is to be used in the construction of furnitureor other things requiring' a metal or wood frame supporft as shown inFigs. 1, 2, 3, 13, I make the wooden supports re proof by painting themwith a' non-combustible paint before moulding, pasting or pouring myarticial ber wood around the frames.

I prepare this re proof paint by mixing the composing ingredients inabout the following proportions` viz: forty parts lime, twelve andone-half parts cooking salt, f* teen parts alum, and thirty-two andonehalf partsv Wolframate of sodium or sodium tungstate.

This fire proof paint I apply to the wood reinforcement or fra-me ofurniture and after it dries I apply my artilicial ber wood by pouringinto prepared form or dies, pasting it on, or by hand modeling thedoughy mass into a desired form.

In constructing furniture, as for instance, the desk 1 shown; in Figs.1, 2, 3, various molds, not shown, are used toenclose the frame 2, afterwhich the pulp is applied to fill the molds and form the desk withdrawer enclosures 3.

Drawers 1 1. are provided that have wood reinforcements 5 that are madere proof.I by application of my paint as applied tol frame 2.

- Legs 6 of frame 2 if desired can be provided With roller casters 7 soas to support the desk 1 clear of the floor.

When my artificial 'ber wood is used in the construction of artificiallimbs it is preferably mixed to a dough that can be modeled into adesired size and form to suit the individual for whom it'is constructed;and a esh color added to the dough corresponding to the natural color ofthe proposed wearer.

When a full arm 8 is formed as shown in Fig. 4, the upper arm isprovided at the shoulder with a socket 9 that can be formed to fit thestub end of the wearers arm. At the elbow and wrist, arm 8 is providedwith ball and socket joints 10, 11 that permit a limited naturalmovement or swing of the joined parts.

In constructing joints 10, 11, the ball portions 10, are formed firstand after they have hardened they are polished to give them a smoothnish. Then the balls are immersed in melted paraiin which when cooledforms a thin coat 12 over the balls. Then the socket ends 11 of the armare formed over the balls; and, after the .socket ends have hardened theparaHn is subjected to heat and permitted to escape from the joints,after which lubricating oil is injected to facilitate a free movement ofparts. By this construction inseparable joints are formed whichconnection of parts can. be made by the artist modeler to assume thegraceful swing or movement of a natural arm.

A different form of joint is shown in Figs. 6, 7 in which a steel ball13 and socket '111 are interposed between the foot and leg l5, 16.

A clearance is left between the foot and lower limb so that there is alimited movement of the foot on ball 14. The lower end of the limb 16has inclined sides 17 that correspond to similar inclined sides 18 onthe foot 15 and these slides in contacting limit the side movement ofthe foot relative to the limb; that is the foot'has a slight sidemovement so that it can assume a flat contact when the wearer istravelling over uneven ground.

When my artificial fiber wood is used in molding or modeling picture or`mirror frames the pulpy can be colored to obtain various artist-iceffects. As seen in Figs. 8, 9 the frame 19 has four shades 20, 21, 22,23 which can be of diiferent colors or if desired can be differentshades of a single color that is mixed with the dough before the frameis formed.V

The frame can be open for a picture, not

shown, or it can be provided with a mirror 24 that has its ed esembedded in the dough; and the back of t e mirror and frame can bestrengthened by cardboard, or by canvas or board backing 25 cementedthereto. Y When my artificial ber wood is to be used in exteriorandinterior decoration the tile or plates can be formed in thin sheets26 which can be placed on a designing table convenient for the artist toengrave or emboss or imprint any desired design thereon, after which thesheets or tile can be secured in place by plastic means.` The sheets canhave a backino 27 of paper, cheap cloth or Wire.

Ihen my artificial ber wood is used in making toilet ap-pliances such'asa bath tub 28, it is molded into the desired-shape and then the entiresurface is subjected to polishing. If desired, the inlet water pipe 29,outlet pipe 30 and over-flow pipe 31 can be molded into the wall of thetub leaving the necessary pipe ends extending for pipe and fixtureconnections.

My artificial ber wood is especiallyadapted to the construction offurniture fixtures requiring great artistic skill in modeling andembossing thereon desired decorative e''ects, as it/ can be reduced tothe right pliableness to be molded into any desired form and retain thatshape without cracking,A

sagging or excessive shrinking..

As seen in Fig. 13 the furniture leg 32 is formed around a straightupright wood support 33 that is made fire proof as previously stated.rlhe leg 32 has an elongated forward extension ,34: unsupported byanything but the tenacity of the iibrous composition, also the backportion of the leg 32 has the enlargements 35, 36 that are formedwithout sagging, (owing to the disposition of the composition to retainits shape when unefi'ected by modeling-force.

In operation my artiicial fiber wood is prepared as. previously statedto pour, plaster or mold, after which it is used by the artist ormodeler to express his artistic ideas.
